To all whom it may concern: H

Be it known that We, RALPH H.- Moore and Josnr'rr T. Bezz-o, citizens ofthe'United State's, residing at Oakland;- in, the" countj of Alameda andState of California,- haveinvented certain new andus'eful Improvementsin Autoihatic Sluicing I Devices for Filters, of which the following isa" speciiication;

In removing. the eakefrom filter clothes in What-are commonly. termedfilter presses} and particularly that'type of press termed"- Sweetlan'd'filter, a wash Water pipe extends" into the filter casing andis-longitudi-fiallv movable and also adapted for oscillation.

i11 order that the Wash Water stream dis eharg'ing' thereirom Willstrikethefaces" of the filter clothesfor their full area and Wash o'rloosenthe collected cake adhering.

to 1 the exterior surface thereof.

Difierent mechanisms have bee1r constructed to accomplishfltliis'reciprocating and oscillating-movement of the 'WiISh Water pipe and thepresent invention relates to such mechanism as has for itsprincipalobjects to provide a simple construction which isautomatie'mits operation, whereby the Wash Water pipe on arriving. attheeiid of its stroke in either direction is autoinatically reversed in itsin'ovement therehy overcoming the necessity! of an attendanlt' requiredwhen manual mechanisms for this purpose are employed.

The present construct-ion is particularly designed for installation inconnection with' certain elements of the manual operating" mechanisinnow supplied with' filter presses of thealo'ov'e type, wherebythe'reeiprocat ing movement is automatically reversed on' the pipearriving at the end of its stroke" in either direction. v

Patented Deere, 1919;

reference is directed to the accompanyingIv n the drawingsgthe numeral-.1 indicatesthe' casing; of the filter press fori'n'ed" with an ening 2'through Which extends the horizontally disposed Wash Water pipe 5,

the same passing through a'stuffing box 3 which prevents? leakagebetween the pipe casing; The pipe is adapted forb'oth' reciprocating,moveinent and osdillatingv movement- Within said opening; 2,- and' at apoint-removed from said glaiid= 3 is secured thereto a: cla np fromWhio'hextends a lateral" arm 6; the same being connected at its free endpreferably through a link mechanism: With a member 7 for imparting; anoscllla-tiiig? movement thro'i'i'gh the arm 6 to the pipe5 Rig-idlysecured to the pipe and stirroundingi the same is athreaded sleeve 8,WhlCl1' has" threaded connection With a threaded operatingi'nut- 9, saidn'ut bein'g' split longitudinally as at 10' and said two halfsectionsheing loosely secured together by bolt's ll passing throughearslQ on said half sections. Compression springsl3- force the halfsections tightly about the sleeve- 8, whereby the threads of the nut- 9engage the threads of the sleeve 8 with considerable friotioln; The nutis" retained from longitudinal-movement with the pipe 5 and sleeve-Shy asuitable curved plate 14-, semicircularin front B'lBVfiiZlOIi andreceivable in an annular groove'or guide 15 in the outer surface-of thenut 9, said plate being supported and retainedin spaced relation fromthe casing-'1} icy-suitable bolts or other meansldexten'di'ng laterallyfrom the cas' ing-.1 atop'posite sides-of the shaft 5; This constructionenables the" non rotation of the-nut -Q to" cause reciprocatinginove'ment of the p pe 5 when said' pipe is" oscillated due to the'op'eration of the arm 6.

Extending upwardly from the plate 1i is'a supp'ortifig arnil? formed inits upper surface with a bearing 18 which is in alinement with a.corresponding bearing 18 formed in the upper end of an arm or supportingbracket 19 extending upwardly from the casing 1, and rotatably mountedin said bearings are the opposite end tubular spindles 20 of anelongated cylindrical casing or pawl trip member 21, which is formed onits inner face with the oppositely disposed longitudinally extendingguide grooves 22, and said casing is provided on its outer surface,adjacent one end, with the oppositely disposed cam surfaces 23 and 241-,the low ends of which are arranged adjacent each other and said cams aredisposed in difierent planes transversely on the member 21. The member21 is also provided at a point opposite the cam surfaces 23 and 2a withan outwardly projecting counterbalance weight or portion 25, and at-oneend of said member 21 the same is provided with hws 26 and 27 whichcooperate respectively with stationary projection 28 on the supportingarm 19 and which cooperating engagement limits the rotating movement ofthe member 21, hereinafter described.

Rotatably mounted at its opposite ends in the tubular spindle 20 of themember 21 is a shaft 29 extending centrally of the member 21, and theportion thereof within the member 21 is threaded as at 30. vOne end ofsaid shaft 29 extends beyond its cooperating spindle 20 and has keyedthereto a driven pinion 31 which intermeshes with a driving gear 32secured by bolts 33 to the nut 9. The connection between said bolts 33and the ears 3 1 on said nut, through which the same pass, permits of aslight movement of the nut forming half sections radially of the gear 32to enable the springs 13 to yieldably maintain the nut forming halfsections in tight frictional engagement with the sleeve 8. The gear 32is preferably in ring annular formation and is disposedcircumferentially of the nut, adjacent one end. The nut 9 at the endopposite said gear 32 is provided with the ratchets 35 disposedcircumferentially thereof, and with which are adapted to contact thelower ends of pawls 36 and .37 pivotally mounted on the support 38extending laterally from the arm 17, said pazwls lying one at eachlongitudinal side of the nut 9, and wit-h their upper crossed endscooperating respectively wit] the cam surfaces 23 and 24:. i

The mechanism for causing a partial rotation of the pawl trip mechanism21 to disengage one of the parwls 36 from the ratchets 35 and toposition the other pawl to cooperate with said ratchets on thereciprocating movement of the pipe 5 to its full limit in one direction,is constructed in the following manner:

Threaded 'on the member 29 within the pawl trip member 21 is a pawl tripoperat ing member 39 formed at diametrically opposite sides with tonguesor fingers 40, one of which is receivable in each of said grooves 22,and said member 39 on opposite faces at diametrically opposite sides isprovided with a projection 411 which are adapted to interlock withcorresponding projections 42 extending outwardly from opposing faces oflimiting nuts 13 having threading engagement with the memben 29 inspaces relative to each other.

The position of the nuts -13 limits the travel of the member 39longitudinally of the shaft 29 on the rotation of the shaft, due to thegear connection with the nut 9.

Lock nuts-4A retain the nuts 43 in their adjusted position, and on thetravel of the member 39 its full distance in either direction, one ofthe lugs 11 thereof engaging a lug 4-2 on one of the nuts 13, preventsfurther travel of the member 39, which operation causes the member 39 tomake a slight rotation with the shaft 29, partially rotating the member21, which in turn causes the operation of the pawls 36 and 37 to releaseone from contact with the ratchets 35 and throw the other in engagementtherewith.

The device being constructed and assem= bled as in the drawings andpositioned as in Figs. 1 and 3, the same operates in the followingmanner:

illotion being imparted to the arm 6 to oscillate the pipe 5, the pawl36 causes a rotative movement of the nut 9 with the pipe owing to thetight frictional contact between the nut 9 and the sleeve 8, but thepawl 36 which is in engagement with the ratchets 35 interrupts therotative movement of the nut 9 in one direction and on the upwardmovement of the arm 6 the action of this pawl in arresting the rotationof the nut 9 causes the nut to impart a slight longitudinal movement tothe pipe On the successive rotative movement of the nut 9 the gear 32carried thereby imparts rotation through the pinion 31 to the shaft 29and this rotative movement of the shaftcauses a longitudinal movement ofthe pawl trip ope-rating member on the shaft 29 as the counter-weight 25holds the trip member 21 in the position as in Fig. 4: of the drawings.v The successive intermittent partial rotation of the shaft 29 causes amovement of the member 39 to its full limit in one direction, at whichtime the lug 11 thereof engages the lug 42 on the retaining nut, andthis engagement locks the member 39 and the retaining nut 43 whichlimits the movement of the member in one direction and on the successivepartial rotation of the shaft 29, the members 10 received in the slot 22cause a partial revolution of the pawl trip member 21, which, in itsmovement, disengages' the pawl 36 from the ratchets 1 fee 5 $4 49 35 andpe'rmitsthe engagement of the pawl 37 therewith.

This operation on successive reciprocations of the arm 6 will cause arotation of the nut 9 in the opposite direction, which will also impartrotative movement to the shaft 29 to cause the member 39 to traveltoward the limiting nut 43 adjacent the opposite end of said shaft 29,at which time a partial revolution will be imparted to the member 21returningit to its former position to disengage the pawl 37 from theratchets and position the pawl 36 to engage therewith.

It will be apparent that the distance between the limiting nuts 43controls the reciprocating movement of the pipe 5, and any variation inthis distance will correspondingly vary the travel of the pipe 5.

Having thus described our invention, what we claim as new and desire toprotect by Letters Patent is 1.
